Fast answer: cheapest fixed tariff for house share UK now

The cheapest fixed tariff for house share UK now is the live fixed deal that gives the lowest estimated total annual cost for your postcode once you include unit rates, standing charges, and any exit fees. Because house shares often have higher combined usage, comparing on total cost (not just the unit rate) is usually the fairest way to choose.

Key takeaway #1

Use your postcode and your meter type to see the fixed tariffs you can actually get. Availability is location-specific.

Key takeaway #2

For house shares, standing charges can matter as much as unit rates—especially if you’re trying to keep bills predictable.

Key takeaway #3

Check exit fees and the fix length. If people might move out, flexibility can be worth paying a little more.

Important: We don’t publish “the cheapest tariff” as a single named deal because fixed tariffs change daily and vary by region, payment method and credit checks. Use the quote tool to see current options for your address.

Check the cheapest fixed deals for your house share

To find the cheapest fixed tariff for a shared home, you need results that match your exact setup. In the UK, fixed tariff prices can vary by:

  • Postcode / region (network costs differ)
  • Payment method (e.g. Direct Debit vs other options)
  • Meter type (credit, prepayment, smart, and some legacy set-ups)
  • Fuel (electric-only, gas-only, or dual fuel)

Tip for house shares: if one person pays the supplier and others reimburse, consider setting the tariff choice and bill-splitting rules in writing (even a shared note) to avoid disputes when rates change or someone moves out.

How to compare fixed tariffs fairly in a UK house share

In a house share, “cheapest” can mean different things depending on how you split bills and how likely it is that people will move during the fix. Use these steps to avoid the most common mistakes.

  1. Start with total annual cost. A low unit rate can look great, but standing charges apply every day regardless of use.
  2. Check the fix length vs your likely move-out dates. If someone is likely to leave, understand whether the contract has exit fees and when they apply.
  3. Confirm the meter setup. Prepayment, smart meters and some older meter types can limit which deals you can take. If you’re unsure, use a recent bill or ask your current supplier.
  4. Choose a payment method everyone can live with. Many fixed deals assume Direct Debit. If the billpayer can’t or won’t pay by DD, your cheapest option may be different.
  5. Agree a splitting method before you switch. Common options are equal split, per-room split, or usage-weighted (harder without sub-meters). Make sure standing charges are included.

Two realistic house-share scenarios (with numbers)

These examples show why “cheapest” depends on how costs are structured. They are illustrative only (not live prices).

  • Scenario A: 4-person share, high usage
    Assume the home uses around 4,200 kWh electricity and 14,000 kWh gas per year combined. A deal with slightly higher standing charges can still be cheaper overall if its unit rates are materially lower at higher usage.
  • Scenario B: 2-person share, lower usage
    Assume around 2,200 kWh electricity and 8,000 kWh gas per year. Here, a tariff with lower standing charges may compete strongly, because fixed daily charges form a bigger share of the bill.

How to split bills fairly (quick options)

  • Equal split: simplest; best if rooms and usage are similar.
  • Per-room split: useful if one person has a bigger room or en-suite.
  • Usage-weighted: fairest in theory, but difficult without sub-metering; can cause friction.
  • Hybrid: split standing charges equally, then split usage costs by an agreed ratio (e.g. 40/30/30).

Good to know: If you’re in an HMO, the landlord may be responsible for some utilities depending on how the property is set up and what the tenancy agreement says. If in doubt, get advice before switching.

Fixed tariff comparison: what to look at (house share edition)

When you compare fixed tariffs, focus on the items that change your total cost and your risk if someone moves out. Use this table as a quick decision aid.

What to compare Why it matters in a house share What to do
Estimated total annual cost Lets you compare like-for-like across different standing charges and unit rates. Use your best usage estimate (or last 12 months) and compare totals, not headlines.
Standing charges Paid daily regardless of use; can feel “unfair” if one person is away often. Decide how you’ll split them (often equally) before you switch.
Unit rates Higher combined usage means unit rates can dominate the bill. If your usage is high, prioritise lower unit rates once standing charges are reasonable.
Exit fees & switching rules Someone moving out can trigger a desire to switch, even if the tenancy continues. Check whether exit fees apply and whether they’re per fuel. Budget for them if plans may change.
Payment method & credit checks Some deals are priced assuming Direct Debit; eligibility can vary by supplier. Choose a method the billpayer can reliably manage to avoid missed payments.
Meter type Prepayment and some older meter types can limit options or require changes. Confirm what you have before applying. If unsure, use a bill or ask your current supplier.

Quick checklist: who a fixed tariff usually suits

  • You want predictability for budgeting in a shared home.
  • Most housemates expect to stay for most of the fix period.
  • You can manage the payment method required (often Direct Debit).
  • You’re happy with a clear process for bill splitting and readings.

Who it may not suit (or needs extra care)

  • Housemates may move frequently (exit fees could become likely).
  • You’re on prepayment and don’t want to change how you pay.
  • You’re unsure who is responsible for utilities under the tenancy/HMO set-up.
  • Cashflow is tight and a fixed Direct Debit could be hard to manage.

Costs, exclusions and common pitfalls (UK house shares)

These are the issues we see most often when shared homes look for the cheapest fixed tariff. A quick check now can prevent a messy dispute later.

Pitfall 1: comparing unit rates only

Two tariffs can have similar unit rates but very different standing charges. In a house share, this changes how “fair” the bill feels if one person is away, and it affects your total annual cost.

Pitfall 2: forgetting exit fees when people move

Some fixed deals include exit fees. If the group wants to switch early (or needs to because of tenancy changes), the fee can wipe out any expected benefit.

Pitfall 3: wrong meter or payment assumptions

House shares can have unusual set-ups (prepayment meters, landlord-managed supplies, or legacy meters). If you apply for a tariff you can’t take, it wastes time and can cause friction with housemates.

Pitfall 4: not agreeing bill responsibility

If the account holder moves out, you may need to update the account name and payment details. Agree who will hold the account and how you’ll handle final readings and deposits between housemates.

Don’t rely on a “typical bill” headline. Energy costs vary by region, property, occupants, usage, and payment method. Use your own consumption if possible, and always sanity-check the estimated totals.

If you’re worried about debt or back-billing

If you’ve moved into a house share and there’s uncertainty about old balances, get clarity before switching. Citizens Advice has UK guidance on billing problems and debt support.

FAQs: cheapest fixed tariffs for UK house shares

What is the cheapest fixed tariff for a house share in the UK right now?

It’s the fixed deal available for your postcode that produces the lowest estimated total cost once unit rates, standing charges, and any exit fees are included. Because fixed tariffs vary by region, meter type and payment method, the cheapest option can’t be stated as one universal tariff name.

Can tenants in a house share switch to a fixed tariff?

Often yes, but it depends on your tenancy agreement and who is responsible for the energy account. If you pay the bills directly to a supplier, you can usually switch. If utilities are included in rent or managed by the landlord, you may not be able to change the tariff yourself.

Do fixed tariffs usually have exit fees, and who pays them in a house share?

Some fixed tariffs have exit fees, others don’t, and terms vary by supplier and product. In practice, the account holder is responsible to the supplier, so housemates should agree in advance how any exit fee would be shared if the household chooses to leave the contract early.

Is a longer fix always cheaper for a house share?

Not always. A longer fix can improve budgeting certainty, but it can be less suitable if housemates may move out or your circumstances might change. Compare based on estimated total cost and flexibility, not just the length of the contract.

What if we have a prepayment meter in our shared house?

Prepayment can reduce the range of fixed deals available and may involve different payment options. You can still compare, but make sure you select the correct meter type. If you’re unsure, check a recent top-up receipt, your meter display, or contact your current supplier.

Do we need everyone’s name on the energy account in a house share?

Not necessarily. Many shared homes have one account holder who pays the supplier and then splits costs with housemates. If you prefer shared responsibility, ask the supplier what options they allow. Either way, it’s sensible to agree how readings, payments and move-out dates will be handled.

How do we estimate usage if we’ve just moved into a house share?

Use any previous bills if available, or start with a reasonable estimate based on property size and number of occupants, then adjust once you have a month or two of meter readings. The most reliable comparison uses your last 12 months’ consumption where possible.

Will switching interrupt our gas or electricity supply?

Switching supplier or tariff should not interrupt your supply in normal circumstances. The process is mainly administrative, though timings can vary. Always keep paying your current supplier until the switch is confirmed, and take meter readings on switch day if you can.

Still unsure? Get a live shortlist by postcode and then check the exit fees, standing charges and payment method before you choose.

We define “cheapest” for this guide as the tariff that gives the lowest estimated total cost for a household once the key price components are included.

  • Included: unit rates, standing charges, tariff length, and any exit fees (where provided in product terms).
  • House share lens: we emphasise predictability, fairness of split costs, and move-out risk.

Limitations (being transparent)

  • We don’t publish live unit rates on this page because they change frequently and vary by postcode and meter type.
  • Your “cheapest” result depends on your usage estimate. If the estimate is off, the ranking can change.
  • Tariff eligibility can depend on credit checks, payment method, and meter compatibility.
